This week: Google won’t penalize you for using multiple markup formats on the same content, the Hummingbird algorithm has nothing to do with spam, and wait until you hear how many web pages Google knows about.
Here’s what happened this week in SEO.
Google Will Index Desktop Sites, Even If They Have AMP
For those (probably rare) websites that only have a desktop and an AMP version, but no responsive mobile version, Google will index the desktop version of the site.
That might come as a surprise to a lot of SEOs.
Google’s Maile Ohye confirmed this week to Jennifer Slegg that AMPed up desktop sites get indexed when they have no mobile alternative.
There are speculations as to why Google has adopted that policy, but the company is silent.
Some people think that the desktop version, which isn’t stripped down like the AMP pages, represents a more “complete” view of the website and therefore deserves to be indexed.
Google will still index the AMP version of the site if that’s the only version that exists.
Google Knows About 130 Trillion Web Pages
Looking for a stat to discuss at the water cooler today? Here’s one: Google knows about 130 trillion web pages.
That’s trillion with a “tr.”
According to Google’s How Search Works page: “Search starts with the web. It’s made up of over 130 trillion individual pages and it’s constantly growing.”
That number is up by 100 trillion pages when Google first launched How Search Works back in 2013.
Keep in mind, though, that the stat doesn’t reflect the number of pages that are in the Google Search index. It only reflects the number of pages that Google knows about.
Google Recipes Guidelines Now Advise to Use AMP HTML
Google recently updated its guidelines on recipes markup to advise you to use AMP HTML.
Here’s what the first guidelines says: “Use AMP HTML (Accelerated Mobile Pages) to build your recipe pages and mark-up the content with structured data to provide rich cards and instant-loading host-specific lists for your recipes.”
And the recipes properties section has been updated as follows: “Build your recipe pages with AMP HTML, and mark up your recipe content with the following properties of the schema.org Recipe type. In addition to the required fields, mark up as many of the recommended fields as possible to drive better engagement in Search.”
Google: Hummingbird Algorithm Isn’t About Spam
Back in 2013, Google announced the release of the Hummingbird update to its search algorithm. That update was designed to make searches faster and more efficient.
Some people thought it was developed as an effort to combat backlink spam. This week on Twitter, John Mueller said that’s not the case.
Specifically, someone asked Mueller the following question: “Did you update Hummingbird as a measure against spam?”

Here’s how he responded: “All our algorithms have to deal with spam, but Hummingbird isn’t specifically for spam.”
Google Won’t Penalize You for Using Multiple Markup Formats on the Same Content
Which one you select depends on what’s best for your website. But what happens if you select more than one option to mark up the same content? Will you get penalized by Google?
A few weeks ago, Jennifer Slegg asked Gary Illyes this question on Twitter: “Is there an issue (ie. spammy structured markup manual action) with marking up the same content using both JSON-LD & microdata?”
Illyes responded as follows: “No, that shouldn’t be a problem.”
